Alpha Lipoic Acid (ALA) is a fat- and water-soluble nutrient with antioxidant activity. A sulfur-containing compound present in human cells, it is required for energy production within the mitochondria and provides protection both inside and outside the cell. ALA has the ability to regenerate and extend the biochemical lifetime of other antioxidants, such as vitamins C and E, as well as glutathione and coenzyme Q10 (CoQ10). As such, it plays a role in fighting oxidative stress and free radical formation. As a coenzyme, ALA is needed to break down glucose for energy metabolism.

This versatile nutrient has been shown to support vascular and connective tissue health, protect cell structures, support the nervous system, help maintain healthy liver function and maintain cholesterol and blood glucose levels within normal ranges. Because of its antioxidant properties and its ability to improve blood vessel circulation to the nerves, ALA has been studied for its ability to improve circulation, particularly in the nervous system.

Alpha lipoic acid can be made in the body but production declines with age. ALA supports healthy aging, helping to neutralize free radicals before they can cause damage to the elastin and collagen in the skin that can be linked to signs of aging and wrinkles. ALA also provides support for althletes by producing energy in muscles and directing calories into energy production.

Research

More than a dozen clinical trials have studied the role of alpha lipoid acid in maintaining healthy nerve function. Findings demonstrate its neuroprotective function, believed to be due to ALA's ability to modulate nitric oxide metabolite activity and to promote healthy microcirculation.
